KEY CASE.

To allwhom it may concern:

"Be it known that I, NATHAN EISEMAN, a citizen of theUnited States, residin at Chicago, in the county of Cookand t-ate of Illinois, have. invented a new and'useful' lected key to be used for insertion into a given lock. A primary object of my invention is to render a protruded key 'unobstructably rotatable with its hook in 'erforming with the key its locking or on ocking function, while holding thecase in the' users hand.

Further objects are to provide an improved construction of the end of the hook "to facilitate attaching a key thereon and prevent its accidental withdrawal; and to provide a highly flexible and durable pintle for suspending the hooks at theirrings on the inner face of the back of the case.

These and other objectsareaccomplished by my improvements illustrated in the accompanying drawing, in which:-

F gure 1-is a view of the keycase in its open condition, showing the hooks in place on the back; j

Figure 2 is a broken view showing the endap on the back before it is folded u n Fig. 1, this view serving to disclose. the pintle-rod feature of my improvement and the manner of applying it to the under face of the flap' and connecting the hooks with the pintle through the flap;

Figures 4' and 5 are broken views, at-

right-angles to each other, of another form of the rotatable hook;

Figure 5 shows the stem or shank of the heck of Figs. 4 and 5 before the hair is formed thereon for union. with a socket;

j construction when providedwith slots 11.

and stitched to the latter, as represente in Figure 3 is a view in elev'ation partly,

Application filed October 1, 1923. Serial No. 686,603.

- stem of Fig. 5 after the stem has been inserted through a blank to be shaped intothe socket-head represented in Figs. 4 and 5; and

Figure dis a broken view showing a blank tobe shaped about the, ball for forn1- ing the socket-headtherefor.

The case proper, of leather "ior other suitable flexible material, is of ordinarygeneral construction, comprising a back 7 and side flaps 8 and 9 adapted to be folded in mutually overlapping relation on the back, where they are fastened together by pressing a socket 8 on one flap over a button 9 on the other, this fastening being well known and as usually employed for the present purpose.

For carrying keys (not shown) on the back 7, I prefer to'provide' on the latter an end-flap 10 to be folded upon the back and stitched thereto, as represented Fig. '1,

'thoughthis is not a necessary feature of my key-case, since the key-carrying medium on the back may involve any other suitable 1 Hooks 12 are provided, as usual, for holding the keys, and terminate at the ends of their stern-portions in rings 13, which are passed through the flap-slots 11 and are hung 'on a pintle-rod 14;, forming a feature of my improvement hereinafter described; and when the pintle is passed through the series of hook-rings projecting through the slots 11 along the inner face of the flap lO,

the latter is folded on the back 7 and fas-' tened, as by the stitches indicated 'at'y15 (Fig. 1) With the hooks thus in place, they may be turned on their axis 14 to protrude beyond the back, .or to' extend in the case to lie flatwise therein as re resented in Fig. 1' for confining keys hooke upon them, as usual, 'to similarly lie flatwise. 7 However, since the hook-rings are so confined about" the pintle as to bindor. obstruct them against movement for turning the hooks out of and into the case otherwise than the directionat right-angles to their axis 14,

manipulation of a key on a protruded hook for its locking or unlocking purpose would be ,hampered with obviously resultantin convenience unless the hook be rendered rotatable with the key so employed. v e

I tobviate this objection byproviding the hook with a joint adapting it to be rotated on. its own axis as well ason the pintle. 4 9

axis.- This may be accomplished by providing a swivel-joint between the stem and ring of the hook, as represented in Fig. 3,

wherein the ring is provided with a collar 16 fitting about the reduced section 12 of the hook-stem, the end of which is upset,-

' as shown at 17, to fasten the hook and ring together in relatively rotatable relation. Another desirable construction of the joint is of the ball-and-socket variety, illustrated in Figs. 4 and 5, wherein a ring 13" is formed onone end of a stem terminating in a leaf-like head 13*, perforated at 13 formed into a ball 17 (Fig. 5"), whereupon the leaves of the head are. shaped about the ball to form a socket 16" therefor.

With either the described swivel orballand-socket joint on a hook, the latter may be turned, as usual, on the pintle to rotrude the. key for insertion into a ock, whereupon it may be freely turned, while the user holds the" key-case flatwise in his hand, because of the hook being rotatable with the key. 7

The form of hook illustrated has its hooking extremity curled inwardly to form a rounded head 18, which better ada ts the hook for its p y in a key-case, y prehighlyfiexible pintle, preferably for a rod composed of rawln'de,

the urpose V whic is both thus flexible and durable; and

when the rod has been inserted through: a series of the hook-rings, as hereinbefore described with relation to the showing in 2, I expand it at intervals, as by stampmg between the rings, to corrugate it and form protuberances 19 between the rings,

of greater diameter than the latter, to con-j shown and described and I do not intend to limit my invention thereto except as pointed out in-the appended claims, in which it is myintention to claim all the novelty .inherent in my invention as broadly as permissible bythestate of the art.

1. A key-case of the character described provided with a key-carrying flap-extension provided with slots at intervalsand-folded upon and secured to the inner face of the case-back, a pintle extending through and confined in said folded flap, and hooks having on their stems rings surrounding the pintle and projecting through said slots, said stems having flexible-joint connections with the rings, rendering the hooks rotatable on their own axes.

' 2. In a key-case of the character described,-

a pintle-rod on the back of the case and on which the rings of the key-ca hooks are strung, said rod being formed 0 highly flexible material and provided with protuberances for spac' said rings apart.

3. Ina key-case oft e character described, av pintle-rod ,formed of rawhide and corrugated to provide ring-spacing protuberances, said rod being face ofthe back of e case and having the rings of the key-ca hooks strung thereon and aced apart y the protuberances formed y the corrugations.
